Definitions
- the present invention relates to a high Cr Ni-based alloy filler material used for welding in a nuclear power plant equipped with pressurized water reactors which operate at a high temperature.
- Patent Document 1 Laid-open Publication of the Japanese National Phase Patent Application
- a high Cr Ni-based alloy filler material which is typically used for heat exchanger tube members for a steam generator in a nuclear power plant equipped a with pressurized water reactor operating at a high temperature of 300 to 350°C, has conventionally been known.
- the high Cr Ni-based alloy filler material disclosed in the Patent Document 1 has a limit to enhance the weld cracking resistance.
- An object of the present invention is to provide a high Cr Ni-based alloy filler material of which weld cracking resistance can sufficiently be increased for which generation of scales is suppressed, and a welding rod for shielded metal arc welding that exhibits sufficiently increased weld cracking resistance.
- a high Cr Ni-based alloy filler material according to the present invention comprises, in percent by weight, C: 0.04% or less, Si: 0.01 to 0.5%, Mn: 7% or less, Cr: 28 to 31.5%, Nb: 0.5% or less, Ta: 0.005 to 3.0%, Fe: 7 to 11%, A1: 0.01 to 0.4%, Ti: 0.01 to 0.45%, V: 0.5% or less, and, as inevitable impurities, P: 0.02% or less, S: 0.015% or less, O: 0.01% or less, N: 0.002 to 0.1%, and the balance: Ni. According to the high Cr Ni-based alloy filler material according to the present invention, the generation of scales can be suppressed, and thus the weld cracking resistance can sufficiently be increased.
- C carbon
- the tensile strength increases as the amount of C increases.
- the stress corrosion cracking resistance decreases as the amount of C increases. Taking the foregoing into consideration, the amount of C is set to 0.04% by weight or less.
- Si acts for deoxidation during welding. Si of 0.01% by weight or more needs to be added. However, the weld hot cracking susceptibility increases as the amount of Si increases. Therefore, the amount of Si is set to 0.01 to 0.5% by weight.
- Mn manganese
- S sulfur
- Mn acts for deoxidation and desulfuration during welding.
- Mn combines with S which gives adverse effect on weld hot cracking resistance, and suppresses weld hot cracking susceptibility.
- Mn is added over 7% by weight, slag fluidity becomes poor during welding, resulting in reduced welding performance. Therefore, the amount of Mn is set to 7% by weight or less.
- Cr chromium
- Nb niobium
- the weld cracking resistance decreases as the amount of Nb increases. Therefore, the amount of Nb is set to 0.5% by weight or less.
- Ta narrows the co-existence temperature range in solid and liquid phases of an alloy at high temperature and increases the weld cracking resistance. To let Ta exhibit the effect thereof, Ta of 0.005% by weight or more needs to be added. However, as the amount of Ta increases, the ductility is reduced although the strength is enhanced. Therefore, the amount of Ta is set to 0.005 to 3.0% by weight.
- Fe iron prevents or inhibits the generation of a scale, which is generated when the Cr content is high.
- the scale is generated remarkably.
- the amount of Fe is set to 7 to 11% by weight.
- Al (aluminum) is used as a deoxidation agent to be used for manufacturing a welding rod by melting process. Also, Al combines with N in a deposited metal and contributes to increasing the strength as an N-stabilizing element. To let Al exhibit such effect, it is necessary to add Al of 0.01% by weight or more. However, when the amount of Al is excessive, slag floats on the surface of a molten pool during TIG-welding or MIG-welding. The slag coheres firmly on the surface of weld metal as a scale film, which is a cause of fusion failure or the like, and thus the welding performance is reduced. Therefore, the upper limit of 0.4% by weight is set on the Al amount. Particularly, after careful consideration for attaining increased welding performance, it has been found that a preferred amount of Al is approximately 0.05 % by weight in order to obtain stable and superior welding performance without generating the scale film even under a high heat input such as plasma TIG welding.
- Ti titanium
- Ti titanium
- TiN titanium
- Ti titanium
- Ti 0.01% by weight or more needs to be added.
- the amount of Ti is set to 0.01 to 0.45% by weight.
- V vanadium
- P phosphorus
- Ni-Ni 3 P or the like eutectic crystal having a low melting point jointly with Ni. Since P increases the weld cracking susceptibility, the smaller amount of P is better, but excessive limitation of P leads to lowered economical efficiency. Therefore, it is necessary to set the amount of P to 0.02% by weight or less.
- S sulfur
- Ni nickel
- P nickel
- S sulfur
- the smaller amount of S is better. Therefore, it is necessary to set the amount of S to 0.015% by weight or less.
- O oxygen
- O is an inevitable impurity which comes from the atmosphere during preparation of the filler material. O gathers in a form of an oxide at the boundary of crystal grain of the weld metal and reduces the high-temperature strength of the boundary of crystal grain. Also, since O increases the welding cracking susceptibility, it is necessary to set the amount of O to 0.01% by weight or less.
- N nitrogen
- TiN nitride with Ti or the like
- One or more sorts of elements selected from B (boron), Zr (zirconium) and rare earth elements are preferably added to the high Cr Ni-based alloy filler material of the present invention in the amount of 0.01% by weight or less.
- B acts to strengthen the boundary of crystal grain since it separates out at the grain boundary earlier than a sulfide which deteriorates the grain boundary under a high temperature.
- B is effective to inhibit the cracking due to reduced ductility under a high temperature.
- B is added in the amount of 0.001 to 0.005% by weight.
- Zr has a strong affinity for O, and is used as a deoxidation agent. However, Zr also has a strong affinity for N, and separates out as ZrN to make the crystal grain much finer, thereby reducing the weld cracking resistance. When an amount of Zr to be added is large, it produces an eutectic compound having a low melting point jointly with Ni, thereby increasing the weld cracking susceptibility.
- the rare earth elements typically include La (lanthanum) and Ce (cerium).
- the rare earth elements demonstrate large deoxidation and desulfuration effects, and act to enhance the grain boundary and thus to inhibit the generation of cracks during hot processing as well as to reduce the welding cracking susceptibility.
- an amount of the rare earth elements is large, they generate an eutectic compound having a low melting point jointly with Ni, resulting in increased welding cracking susceptibility.
- Each of B, Zr and the rare earth elements acts to enhance the weld cracking resistance. The same effect can be obtained by adding a combination thereof. However, excessive addition increases the welding cracking susceptibility. Therefore, one or more sorts of elements selected from B, Zr and rare earth elements are preferably added in the total amount of 0.01% by weight or less.
- Ca (calcium) and Mg (magnesium) are preferably added to the high Cr Ni-based alloy filler material of the present invention.
- Ca and Mg demonstrate strong deoxidation and desulfuration effects. Ordinarily a small amount of Ca and Mg is included in a filler material. However, Ca and Mg have a strong affinity for O. Therefore, unless the amount thereof is limited to less than 0.01% by weight, Ca and Mg will cause a scale film to be formed in TIG welding and MIG-welding. Therefore, the amount of each of Ca and Mg is set to 0.01% by weight or less.
- weld metal means a metal of a welded portion in which welding rod and base metal are molten with each other and from which slag is removed. That is, the weld metal has the chemical composition comprising, in percent by weight, C: 0.04% or less, Si: 0.01 to 0.50, Mn: 7% or less, Cr: 28 to 31.5%, Nb: 0.5% or less, Ta: 0.005 to 3.0%, Fe: 7 to 11%, V: 0.
- the weld metal of the welding rod for shielded metal arc welding in accordance with the present invention further includes Al: 0.01 to 0.4%, Ti: 0.01 to 0.45%; one or more sorts of elements selected from B, Zr and rare earth elements: 0.01% or less.
- the behavior and effect of each element as well as the reason for limiting the content of each element are the same as those for the high Cr Ni-based alloy filler material as described above.
- the weld metal formed by shielded metal are welding in accordance with the present invention has a chemical composition comprising, in percent by weight, C: 0.04% or less, Si: 0.01 to 0.5%, Mn: 7% or less, Cr: 28 to 31.5%, Nb: 0.5% or less, Ta: 0.005 to 3.0%, Fe: 7 to 11%, V: 0.5% or less; as inevitable impurities P: 0.02% or less, S: 0.015% or less, N: 0.002 to 0.1%; and the balance: Ni.
- the weld metal further includes A1: 0.01 to 0.4% by weight, Ti: 0.01 to 0.45% by weight, one or more sorts of elements selected from B, Zr and rare earth elements: 0.01% by weight or less.
- a support T-shape fillet weld was made by TIG welding using a high Cr Ni-based alloy filler material blended with various elements as shown in Table 1, and the generation of a scale and the state of bead cracking were examined.
- the support T-shape fillet welding was carried out in conformity to JIS-Z3153 added with a minor modification.
- support beads 3 and test beads 4 were made using cladding materials 1 and 2, each of which was formed on a carbon steel plate by duplex cladding welding using the test welding materials, combined in a T-like shape interposed by a gap.
- Table 1 shows the generation of scale and the state of bead cracking. The state of bead cracking was evaluated and classified into the following three categories:
- Figs. 2(a) and 2(b) show an electron microscopic picture of a weld surface of test beads of the example 3 in the above tests and a result of the qualitative analysis by means of SEM-EDX respectively.
- Figs. 3(a) and 3(b) and Fig. 4(a) and 4(b) show an electron microscopic picture of a weld surface of the test beads in the comparative example 4 and comparative example 7 and a result of qualitative analysis by means of SEM-EDX in the above tests respectively.
- Fig. 2 (a) demonstrates that, in the example 3, a scale was not generated on the weld surface of the test bead.
- Fig. 4(a) demonstrate that, in the comparative examples 4, 7, a scale was generated on the weld surface of the test bead. Also, Fig. 3(b) demonstrates that, in the comparative example 4, the amount of Ti on the weld surface is large and Fig. 4(b) demonstrates that, in the comparative example 7, the amount of Al on the weld surface is large. From the above, the present invention prevents the generation of a scale by appropriately controlling the amount of Al and Ti.
- the high Cr Ni-based alloy filler material according to the present invention inhibits the generation of scales and enhances the weld cracking resistance.
